In this presentation, we study various aspects of the wind turbines or wind mills. We optimize the performances of both a single wind turbine and a wind farm, collectively. We study the nozzles on the blades and all the variations and accessories for the operation of a nozzle. We also explore flow p ...

A method and an arrangement for a forecast of wind-resources of a wind-farm are provided. The forecast is done by a numerical weather-prediction-tool, the weather-prediction-tool using a long-term data-set of meteorological data. The data are related to the location of the wind-farm. A wind-speed me ...

The foundation has a sea cable feed through, which is provided at a height within a range of 3.5 meters to 5 meters over a sea bed (20). The sea cable feed through is designed for guiding sea cables (24) under an angle of forty degrees to the foundation from a side of the sea bed diagonally upwards. ...
